This curious thread is about acoustics not about speakers brand name...

Then it is not a "curious " thread but an acoustics question thread...

 You are welcome to post your experience about acoustics ...

My deepest regards...

@mambacfa your post got lost in this curious thread,

@mambacfa your post got lost in this curious thread, but I agree with you 100%. I learned about the Lii audio speakers a few years ago and purchased the cheaper 6 inch models thinking I was basically throwing money away. I put them into simple open baffles and they really surprised me. The whole range of the audio spectrum certainly was not there, but there was a quality of immediacy that was captivating. I later got a pair of the F-15s and put them in a nicer open baffle and they remain as one of my top systems to this day. They are great with low power tube amps For instance.

A thing i discovered thinking about the two groups opposing each others in audio:

The so called subjectivist and the objectivist was their common ignorance about the importance of the acoustics and psycho-acoustics concepts and parameters because they are focus on the gear frequency response or their "taste" when "hearing" a piece of gear...

 But the frequency response as analysed by ASR afficionados or as experienced by audiophile ears in a living room dont tell the story that must be tell at all...

 

Now what means the ratio ASW/LV and why it matters so much more than the price of your speakers.... This is the subject of the thread i begun ....

 

 

For example when i did the mechanical tuning of my room to recover the spatial attribute of the sound i ought to be dealing with the trade-off between the frequency responses of the room/speakers for the timbre perception versus the spatial localization of the sounds sources.

It was a trade-off an imperfect mechanical game of tuning...

I learned a lot...

but the only way to do it optimally without losing in this trade -off between timbre accuracy and spatial attributes cannot be mechanical...We need psycho-acoustics measures of the head and inner ears canals and the application of filters which will makes us able to recover the loss of acoustic information which is there in the recording but lost in the speakers/ room stereo unnatural situation ...

 

This is why it is very important for any audiophile to read articles by Dr. Edgar Choueiri to understand clearly the acoustic challenge at play, especially if unlike me you have not the time , the dedicated room and  you are not interested in investing so much time in the tuning of a room mechanically...

 

 

few harassing posters tried to derail it...

I gave my 19 minutes to watch that video and then I felt I had the right to say what I thought. But oh well. I didn't know the rule that you can post whatever and I need to shut up about it if I have a negative opinion about the video. 

Go elsewhere if you are not interested by acoustics...

blush yes sir

Imagine you yourself  start a serious  thread and few harassing posters tried to derail it...

Imagine my only post in this thread of yours is about how dumb the youtube video  which you used is, so dumb that this youtuber is certainly  trolling us... 

Then if you put yourself in my shoes  won’t you feel attacked as the OP of this thread  by me posting  as an answer that you had just post a so evidently dumb video designed probably by a troll ?

 

 

 

Go elsewhere if you are not interested by acoustics...

And dont play the surprize game ....it is called hypocrisy...

 

I just posted few days ago in a thread of yours without  any insinuation a good post answering your question , are you not able to act as a gentleman in the same way ?

 

 

I did not say you were trolling. That’s what I clarified exactly. If you still twist my words, that’s not my problem. I never in this thread said or implied that you were trolling. 

 Why the frequency responses of a speakers design is not enough to know the speakers potential peak performance ?
 
Because of the room frequency response in which it will be working...
 
 
But why the room frequency response is not enough to reach  the optimal sound quality  experience ?
 
 
Because there is psycho-acoustics parameters...
 
Because stereo listening is completely unnatural  for our hearing sense...We must use this unnatural situation for the best...
 
 
 Then What ?
 
 Then you can tune mechanically  your room in relation to your own hearing perception...
 
 I did it mechanically using Helmholtz resonators tunable and specifically located grid of resonators...I tuned them on a long period  in a self correcting way i had 100....
 
Doing so i used in a mechanical way  the psycho-acoustics principle related to the way each of our ears perceived each speakers timing and location ...
 
I learn acoustics doing it but it is not esthetical nor practical especially in a living room if you have no time ( i was retired)....
 
 
 Then the only optimal way is after buying speakers, after doing the minimal acoustics treatment and control you can read Dr. Choueiri articles and methods using psycho-acoustics in a non mechanical way but with specific filters to optimize your speakers/room for your specific hearing...
 
 
There is no other way i know of....

I did not say you were trolling. That's what I clarified exactly. If you still twist my words, that's not my problem. I never in this thread said or implied that you were trolling. 

I watched this video. All 19 minutes. 19  minutes I will never get back. I can tell you 10 + 1 reasons why it's dumb. My, my, praising Andrew Robinson. He is shallow and wrong in so many ways. (I am ignorant about 99.99% of all things and anything I would say about it would be dumb. The things is, I know it and I wouldn't make a video about things I know very little about for 1 million subscribers.)

Here is what I did just now. I watched 5 random minutes of it again. It is so dumb, I cannot even begin. But get this: I am saying this on this forum. Sure, the guy makes good points - for beginners. But the way he makes it is just dumb. Is it subjective (what is dumb)? Absolutely. It is just painful for me to watch. I am by no means an audiophile expert and that makes it even more obvious. 

Now the elephant in the room is your personal insults. Totally unnecessary. I don't know why you have the need to attack people who have a different opinion than you do. I didn't form an opinion about you but about the link you posted. 

Do I care about your personal attacks? No. I am just tired of them. It makes people avoid your posts. 

Now i go back to serious matter with a question  :

If the timing and directionality of reflections are critical, if early lateral reflections boost ASW, while late lateral and rear reflections boost LEV, then no matter which is the price or the design of your speakers, there are acoustical parameters that makes us able to transform completely our reviewing impressions about any speakers, then what matter the most acoustics parameters controls or a slight speakers design upgrade or price upgrade ?

Knowing how to pose the question is already the answer...

This simple discovery by the youtuber of my first video, who seems to be less dumb and of better good faith than some troll post in my thread, was the matter of my thread...

 

It is evident that each one of us, as the person in my first video, one day each one of us  as beginner we discovered that speakers locations and the space we are with transform or had an impact on our evaluation of speakers workings ...

Are we dumb because we are able to speak about it and are we troll because we post about this ?

 

 This is why i used this video...

 

 

 

It is evident that this man in this video is not a mature audiophile but an ordinary beginner not a "troll" as you seem to be with few others here derailling the thread with no positive comment...

I did not used this video to troll myself as you insinuated qualifying the video of "dumb video" then attributing this quality by extension to me the OP  when i  used it to speak about acoustics importance and meanings....

I will takes back the apology i gave you few days ago thinking that you were a good faith person...

The underlined part of your post reveal how hypocrital you are and conscious about the way to push the right button to derail my thread with some others which with you banded  with...

I gave you no respect for that and for your past trolling against me either...

 

 

when I said "Pure trolling" it was referencing the dumb video not the post. But I doubt it will help. 

@gano I got your point. This is an interesting guy. As you say, seems to know a lot about cameras. He makes lots of camera videos, a random audio video and, apparently, sells what he calls "luxury hot sauce"- its called Oliveum and is very pricey. No word on whether cheap sauce from China is just as hot.

when I said "Pure trolling" it was referencing the dumb video not the post. But I doubt it will help.

It seems that some had not understood the lesson this naive audiophile go trough...

He discover that room acoustic even if it is only speakers location makes the greatest differences between speakers in a similar bracket price ...

 Qualifying him of trolling is preposterous...

My thread is not, nor this youtube video, motivated by trolling...

I have little patience for this accusations by the way....

 

It is acoustics the greatest factor and the more impactful one ....Especially if we compare speakers in the same bracket price...

 

 As a personal anecdote:

My friend own big  Magnepan in a living room with no acoustics control...

My past speakers  Mission in my acoustics controlled room were way better  than his Magnepan...

To be clear the Magnepan well installed acoustically will beat the hell of my Mission...(  but he was only able to  produce a wall of sound where i was able to create a sound completely enveloping the listener from all side not because Mission speakers are better than Magnepan, they are not, but because of the power of acoustics parameters control)

Then compared to a living room with no acoustic optimization for the Magnepan, my Mission in a very good optimization room for them beat them by a huge margin...

 

The lesson of this video is a beginners audiophile discover the power of acoustics..

Not the law of diminishing return...

Not the overpricing of speakers...

Not the way to troll ....

It is why i used this video...

I dont like accusation of trolling...

 

 

I am here laughing at this topic for 3 reasons:

1) What the video guy said has both a lot of what I'll call general truth; and also a bit of what I'll call specific truth... The general truth is basically just a take on the law of diminishing returns; that is, that the expectation he had was that a significant (to him) cost difference should have equated to a similarly significant performance difference. And his reality (which, after all is what really matters, our own individual perceptions and opinion) did not show that direct correlation. I feel like the umbrage being felt by some here is at least partially a result of the notion that for many in the audiophile community, having a 'law of diminishing returns' at all is anathema to the hobby itself. I mean, it's almost a Biblical level commandment that a TRUE Audiophile HAS TO hear significant differences between different equipment - and ABSOLUTELY MUST hear a huge difference if additional monies have been spent...

I'll point to a quote from mswale just 2 posts prior to mine:

"I have no idea how he can not tell a difference between the lowest cost and highest cost speaker..."

Note this quote does not mention brand, model, features, speaker size / design / driver type, etc. - anything that might directly differentiate sound quality. Only cost. (sorry, mswale, not picking on you - this just caught my attention, as your comment was actually written; instead of just something that most of the other more negative commentors were thinking while they commented - but didn't actually include in their comment...)

2) Now for the 'specific truth' part (which I am surprised I did not see anyone else point out yet). The guy compared 3 amps in a cost range of about $1000 max; and speakers with a cost range of about $800 I think was the difference between highest and lowest (?)... that's not a huge difference, IMO (and look now, I am kind of taking the opposite position of #1, LOL). And, to be fair, although he said he really didn't hear any tangible difference in the amps - he was talking about specifically when using all the same features, etc. He did say that (obviously) engaging the room correction and equalization features on the top amp made an obvious difference in sound. And again, in fairness all the speakers he tested were of a very similar type (1 or 2-way bookshelves); he didn't put the KEF s against Klipsch Jubilees (for example) and then claim not to hear any difference. 

So, while I feel like what was said in the video has some general truth to it, it also needs to be said that the truthfulness of the video is specific to the rather limited range of cost... and of both the total quantity of equipment tested, and the lack of major differentiation (at least with the speakers) in terms of equipment design, etc.

Last thing that brings a chuckle is why anyone would get upset out of this guys opinion..? I don't feel like he is going to dissuade anyone from interest in this hobby; at least not anyone with serious intentions. Heck, even though I agree with some of his premise on the whole 'law of diminishing returns' thing... my own decidedly non - 'audiophile level' vintage system has been a journey of acquiring gear I desired, then evaluation of performance in my particular home environment...  and yes, changing out pieces, brands or models, even things like cables (!) for what usually ended up being more expensive, more reputable, and better sounding alternatives. So, essentially the same general process as a true 'audiophile'... just (admittedly) the combination of my enjoyment level / hearing quality due to age / dedication, if you will - and desire to stay in that 'vintage' 1960s - 1970s time period... leveled out at a place where I have some very nice equipment, with what most people would consider a very nice sound... just not at that definitive true audiophile level.

I'm equally sure there are others out there whose interest level, etc. will take them all the way into the audiophile realm. And there's nothing wrong with that.

 

Really weird he found no value with the highly praised Kef’s

I haven’t watched any other videos of his, just browsed, he is apparently a camera expert. Imagine if he said a flipphone takes better pictures than a Canon 5D. That’s pretty much this video for hifi. Pure trolling. 

Who knew if you moved speakers around it changed the sound? wink

Did you see the speaker wire used? Looks like cheap came with my $50 speaker wire. Also how he stacked them, had them side by side, reflecting off a table. 

Did he break in any of the speakers or amp? I know horn speakers (klipsch) can sound like poo when brand new, they need time to mellow. 

I have no idea how he can not tell a difference between the lowest cost and highest cost speaker. No use of any SPL device to make sure you are matching volumes. Typically people will pick the loudest speaker, regardless of sound quality. 

Really weird he found no value with the highly praised Kef's.

...anyway...see y'all on the screens, J
 

There is a better road than the mechanical tuning of a room with a grid of Helmholtz resonators as i did for sure ( not esthethical and not suited for a living room )...cool

The methods used by Dr. Edgar Choueiri  will be more efficient using basic psycho-acoustic laws to compensate  for the fundamental flaws of any stereo system if your room is minimally under acoustics  control ( the right balance between absorption/reflection/diffusion)...

 

Those interested by acoustics with stereo system must read his articles...

Those interested by acoustics experiments must read about sound waves  reflection controls lateral and back reflection powerful impact  and pressure zone distribution control with Helmholtz resonators...

 

Upgrading may be useless  if you ignore acoustics....

 

 

 

 

 

 
 

 

 

For physical acoustics:

Any presence of a phantom speaker   phantom Speaker a +speaker A  and speaker B + phantom speaker b is the result of distortion caused by "speaker boundary interference effect" as well explained by my first acoustician video...

 

 

For psycho-acoustics:

We have 2 ears : then the speaker A will create by time delay for each ear a phantom speaker image a and the same for speaker B and his image b for the  other ear...

 

 

Then the phantom image of speakers is not only the result of acoustical physical conditions but result in a stereo system by the way each ears will perceive each speakers with a time delay...

 

These facts illustrate how complex is small room acoustics and i used these facts with great result  creating  an holographical surround space with my stereo system...

 

In a word distortion is not a simple negative physical fact resulting from boundary interference effect but result  also of our body organization (2 Ears) perceiving unnaturally the same sound from 2 sources (stereo system) ...

We must not simply  eliminate distortion then  , we must  learn how to control it in our system/room.... 

 

 It is not enough to understand physical acoustics, we must understand basic psycho-acoustics and learn how to use it...

 This is why the balance ratio between LEV and ASW, between listener envelopment parameters and source width parameters  ask for more knowledge (reflections controls and pressure zones distribution controls)   than  just basic physical acoustics about speakers placement  as illustrated by my first acoustician video...

 

 

 

 

 

 

If you don't have the bass right you've got nothing. Everthing else is secondary.

This can easily be put to the test.  Disconnect your left & right two way speakers but leave your sub hooked up and listen to a track you like and then do vice versa (unhook sub and leave the two ways connected).  Personally, I would prefer the second option.

@asvjerry 

Jerry, you are a wordmaster in my book. 
 

The three cheek notion captured my attention. Interesting and mildly unsettling, but always entertaining.

 

Thanks for keeping it light. As a recovering high-strung crybaby (still on double secret probation) I need all the help I can get!


Shine on, Jerry.

I have compared lower budget with mid fi. They sound good. For many people, good enough. However, in my opinion, the quickness, the rhythm, the bass control, to keep detail in a way that it's just not music, but a remarkable experience every time you listen is not there like it is with the more expensive Hi Fi.

Lowest cost speaker: get the Lii 15" full range drivers and mount each on a plywood board. Connect your drivers directly to your speaker taps. Simplest and best sounding speaker for the money ($500 including the plywood.) Sound is holographic. No money wasted on shiny cabinet, additional drivers, crossover networks and speaker connectors. Want even more bass? Get a sub. You may not need it. 

It’s nice that anyone can publish anything they want about anything to the internet these days.  A lot of it is more interesting than junk put on tv and movies.  
 

One guy passed gas and made a 15 minute video covering it in great detail. 
 

Just kidding.  But I bet someone somewhere has done that. 
 

That video appears to have more traction than most threads here.   So it was apparently of interest to  more than most anything discussed here.  Nice!

What is great about this video is he is a professional photographer and on a whim was using dsp.sounding out the room and doing corrections.speaker placement  no expensive cables and amplifiers with low  thd . Very efficient speakers with low cost and the 10% rule of it takes alot of $$$  to get the last 10%. What a great era with dsp. Enjoy the experience and the experiments.ill bet he could teach some of us about photography. Enjoy the music.

+1@mahgister

Dealing with Entry Level participants in any hobby/business/sport/activity can be bewildering and frustrating for the Experienced, unless you/we use empathy and try to remember what it was like starting out. At least the proposed $300 system in the video would be better than most Bluetooth speakers or whatever the Masses are listening to… (I think?)

 

 

The video about sound reflection in rooms.

The tweeter is very directional and easily controlled. On the other hand...think about the bass signal being sent out of the subwoofer directly and then reflected off the back wall. At the same time a bass wave is sent out of the main speaker AND another wave is sent out the port or ports of both the main and the sub.. All bass sources arrive at different times. What a mess. Muddy bass is the result and moving speakers around won't fix this problem. 

THIS is the most difficult to understand and control and the biggest singular thing that makes music sound clear, dynamic and impactful. If you don't have the bass right you've got nothing. Everthing else is secondary.

I doubt a curious budding audiophile going to learn much from this, I'd hope they discovered what this guy discovered far sooner into the journey. 

Andrew Robinson is the worst combination, arrogant, lazy and ignorant. He doesn't even care to learn the basics to be useful in any way.

The acoustics principles are not only ignored but the way we can use them concretely are very complex to master in all their interaction...

For example how can we act on the acoustical material content of a room , with his peculiar geometry,topology, to create a balance ratio between the listener envelopment and the apparent width of the sound source ? How can we use the reverberation time to do this? Why are we in the obligation to investigate how do this instead of upgrading without end ?

A good gear piece design cannot replace acoustics controls, this is why. 

 I have my own answer to this appropriate for my room and ears. There is many other answers possible... Acoustics of small room is very complex matter, only ignorant can claim as above that everybody know this...Buying acoustics panels is not enough in most room case  by the way ....

If those bashing the youtuber of my video and myself because we are faulty to  suggest a reflection road about a complex problem, if those  can understand even the way to pose the problem and know already  the answer, they can answer for the benefit of all or go on insulting me and others giving sarcasms instead of thinking...

 

 

 

By the way laoman come in any thread i answer with insults even few times in my private mail since  more than one year... His history contribution of attacks  is easy to see if you go back in his posts history...

 

 

 

 

 

No wonder young people don't like audiophiles, just read through the posts on this.

I haven't even watched the video and can tell you are all so removed from the people just starting in the hobby. 

If you don't find anything of value in the video, then you're not the target audience. So don’t complain its not always about you, just move on.

If there is misleading information feel free to educate in a respectful way don’t bash the person for not knowing.

I'll stand by my original comment, I don't find anything of value in this video-I don't think I'm alone in that conclusion. If that makes me stupid so be it. I'll also say that the concept of acoustics is well known, I suspect, to those who frequent this forum, even if we don't post about it over and over. As I also said, if the OP learned something from this video, good for him, I'm sure this YouTuber has other material he might find beneficial. I was unimpressed-I thought I might be entitled to that opinion and I thought posting the video might be an invitation to comment-obviously that was an incorrect assumption. 

I'll take some responsibility for this little detour. I should have known better than to engage. As @abnerjack pointed out, in a very kind way, these interactions end up with this sort of pointless name calling with unusual frequency. Should have just ignored the post. 

This is the second thread today that I feel the need to throw some comment into.

There are multiple things going on in this thread that need clarification. 

I have read the postings prior to @kerrybh comments multiple times. I don’t see that @mahgister called anyone stupid. He did point out that certain actions and conclusions can be stupid. That is true, but does not mean that the person is stupid. If we want to keep things civil, let's try to see the intent of the posting and the meaning, and not word groups that we find offensive. I will admit that @mahgister can be difficult to digest and his style of comment may be not always be as polite as it could be. I do think he has valuable things to say that are worth trying to understand.

I am an old guy >75 and have tinnitus and plenty of other health issues. I have enough trouble going from day to day and trying to decide if what I hear is different than what I heard yesterday with the same song playing in the same environment with the same equipment. I value what @mahgister has to say whenever he comments in any thread. I think he has found a way to make his system in his environment sound good to him for daily listening for whatever music he wants to listen to. As he has said many times; he cannot really solve anyone else’s system problems without a long time in their environment with their equipment and their hearing.

I appreciate comments from many participating members regarding gear and what they find pleasing, but reserve judgement about what that exactly means. I do not think there is any ultimate component, or ultimate system that makes music sound right to everyone regardless of cost. Each piece interacts with every other piece and the room to present a particular presentation. That may be what works for your sense of what the music should sound like, and good for you. I may not like that presentation at all. Is one of these the correct presentation that the original artist intended? I don’t know how to judge that. I also don’t know that the original artist could tell me what they think it should sound like in a way that I could understand and duplicate. What level of perception should each instrument or tone have at each particular time during the piece relative to the other sounds being presented. I  wasn’t there during that performance, and do not know all the interactions and discussions between the equipment managers, sound engineers, and mixing engineers to know what compromises were made and what each thought they were trying to achieve. I can only try to get the best presentation that I am comfortable with and try to feel the emotional content and impact that the piece contains.

As I make changes in my present modest system, I am trying to find a presentation that I am comfortable with, taking into consideration the constraints of my environment and hearing. All of the ”audiophile” terms of sound stage depth and width and instrument placement all play a role, but exactly what I am hearing and what I want from the sound is the ultimate goal. In my playing with components and connections I can affect different aspects of the overall presentation, but I can’t say that I have found any magic formula that hits my audio nirvana. I am jealous of @mahgister that he has found his.

And we wonder why this space is shrinking when people shun practical acoustic principles for feel good magical Nirvana... @mahgister they wont get it that the room is the ultimate demon of the equation and trying to be purposefully blind to that and throw money at purchasing stuff just because of G.A.S is just a route to many examples of unfulfilled gear addicts 

"This video will inform beginners to think about  before throwing money and study basics acoustics BEFORE upgrading."

No, This video does not educate anyone about anything. The only thing it does is to show that everyone is trying to achieve 5 minutes of fame, even the ignorant.

"By the way i posted this video because i recognized myself." We all recognised you as well.

Now i will suggest a three minute videos by a pro-acoustician to understand why the balance between diffusion/absorption/reflection matter...

This video do not cover the way we can use reflection....It only set the stage...

 

But this explain why our youtuber in the first video was flabbergasted by the speakers difference in slight different location...Imagine now larger acoustic difference  and the huge impact of  other parameters than just location ...

https://www.youtube.com/watch?v=JPYt10zrclQ

 

 My three videos are only a beginning of thinking about the basics...

I will wait for others impressions...

 

Now an interesting 5 minute video with an acoustician about an underestimated problem well explained :

https://www.youtube.com/watch?v=P6N3uXxdYFs

 

Now this 5 minute is very basic....

It takes me a long time to use this pressures zones and reflections...

I did not had the knowledge of this acoustician, i learn it bit by bit,  i only experimented in my room for 2 years 7 Day on 7 and learn how to use these zones to my liking ...

This is way more important  most of the times than the difference of price between 2 speakers, as illustrated by the youtuber  discovering it in my first video....

 

I just started a thread using an interesting video with a simple lesson, valuable for many... (By the way there is way more in acoustics concepts than placing speakers but it is a beginning )

 Then comes someone mocking the youtuber and  Andrew Robinson,me  for using this video of a sincere ordinary perso0n relating his experience and this  with nothing of value in his post...

 I answered it, explaining why attacking people for the sake of it instead of thinking is stupid...

 Now , you had already few times attacked my character in the past and now with no arguments pertaining to this thread , and you come again "psychanalysing" my right to answer...

 Who pollute this questioning thread ?

me ?

Rest assure i dont have any persecution complex, simply many people gangbang the one who is a bit different...

My thread is adressing a question...

If you are not here to answer it  why are you here doctor ? For a gangbang ?

 I am interested to discuss the astonishing many ways acoustics parameters impact any speakers evaluation..

If i start another thread by chance, will you come again after another who will mock another youtuber,and me using it  with the same "psychanalysis" or will you use your brain for thinking instead of veiled sarcasms, false politeness, allusions etc ?

That is my question for you...

 

 

 

 

I will say this, your constant bickering is quite distracting and saps positive energy from a discussion.
